I personally would not want a canadian release any more than UK release for original US vinyl, I would never buy one (even at a much lower price). The only time I would buy a canadian or other non-US release is a) if it is a song / alternate mix not available on us b ) if the group was originally not from the US and it is the first local pre-us press or c) it comes with a cool pic sleeve. For example, I recently bought a german release of the Lovells on Brent that had an alternate, German-only b-side. I do understand how more specialized collectors (e.g. motown collectors) might want releases from other countries as an oddity, but I don't think that applies to most collectors. Everyone here is talking about the canadian releases of equal value, but I think there are a lot of people like me, which would explain why Pete gets a lower price.
There was that cool Charmaines 45 on ebay recently that was on a canadian label only, it had a maple leaf on the label.
